Title: Optical scanning device
Inventor: HISA FUMIYA
IPC: G02B26/10
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To minimize damage due to contacting even if a radial bearing makes a touch owing to a shock, etc., during rotation. SOLUTION: A shaft 54 consists of a center shaft 72 fixed to a motor housing 58 and a movable shaft 66 which is arranged rotatably on the center shaft 72 through ball bearings 70 and 71 allowing smooth rotation, so if a rotor 52 touches the flank of the shaft 54 owing to a large external shock during the rotation of the motor, the movable shaft 66 rotates on the center shaft 72 together with the rotor 52. Therefore, an excessively large impact force can be prevented from being applied to the shaft 54. The movable shaft 66 rotates together with the rotor 52 and then the dynamic balance is prevented from becoming worse to damage a control circuit board.

Abstract: PURPOSE:To reduce the optical reflectivity of an end face and to lessen a cou pling loss of a light amplifier with a fiber by limiting an angle of a face on which a slanting waveguide structure is in contact with a window structure outside the waveguide structure. CONSTITUTION:The outside of a slanting optical waveguide structure is made a window structure 12 and, moreover, both end faces for emission and incidence are coated with a light reflection preventing film 13. Therefore the reflectivity can be reduced equivalently with excellent reproducibility. On the occasion, an angle of a face on which the slanting optical waveguide structure and the window end face structure 12 are in contact with each other is limited so that the relationship of n1sintheta1=n2sintheta2, theta1EPSILON0, be established when the incident angle on a side face on which an active layer 3 is in contact with the window structure 12 is denoted by theta1, the incident angle on the end face of the window structure 12 by theta2, the refractive index of the active layer 3 by n1 and the light refractive index of the window structure 12 by n2. In the end face of the window structure on the opposite side, accordingly, light is emitted in the same direction as that of advance of the light incident thereon and therefore coupling with a fiber is facilitated more.
